TECHNICAL FIELD

The present invention relates to agricultural apparatuses, systems, and methods. More particularly, the present invention relates to agricultural apparatuses, systems, and methods for processing produce. Even more particularly, the present invention relates to agricultural apparatuses, systems, and methods for packing processed produce.

BACKGROUND ART

The currently existing art involves several machines for packing leafy produce, such as “spring mix,” spinach, lettuce, endive, arugula, mache, herbs, and the like. One such invention is a packing machine which fills a container with leafy produce, fits a lid onto such container having the produce, but damages the leafy produce at the rim of the container, thereby shortening the shelf life of the product. This problem in the related art occurs, because the leafy produce has a tendency to spring back upon loading into the container, to overhang the rim of the container, and to be subsequently damaged during fitting of the lid. To counteract this adverse result, agricultural processors have used manual labor for “post-packing” the leafy produce, e.g., using a production line of approximately six gloved workers who manually reposition the leafy produce in the container prior to thereon fitting the lid. Thus, a long-felt need is seen to exist for an automated apparatus, a system, and a method for efficiently packing leafy produce, eliminating damage thereto, and minimizing processing time.

MODES FOR CARRYING OUT THE INVENTION

FIG. 1 illustrates, in a perspective view, an automated packing system 1000, comprising an automated packing apparatus 100, in accordance with the present invention. The automated apparatus 100 for packing leafy produce 10 into a tray 20, comprises at least one plunger 30, each at least one plunger 30 having at least one actuator arm 40 and at least one footpad 50, the at least one footpad 50 having an upper surface 50 a and a lower surface 50 b, being in moveable relation to the at least one respective actuator arm 40, for contacting the leafy produce 10. The moveable relation comprises a structure 40 a (not shown) for articulating the at least one footpad 50 about each respective at least one actuator arm 40. The articulating structure 40 a is disposed at a location selected from a group consisting essentially of a periphery of the footpad 50 at the upper surface 50 a, a centerline of the footpad 50 at the upper surface 50 a, and a location between a centerline of the footpad 50 and a periphery of the footpad 50. The system 1000 is shown in FIG. 1 with a set of plungers 30, e.g., primary plungers, with a support frame 1001, with a hopper 80, comprising a primary chute 1002 and a secondary chute (pant-leg chute) 1003 for facilitating filling of two trays at a given filling interval, and a feeder 90, comprising a feature such as a product transfer (funnel) 120, for clarity and by example only. The primary chute 1002 comprises a flop gate 1002 a and a flop gate actuator 1002 b, as shown in FIG. 12 which is described, infra, and a flop gate control device 1002 c, such as a solenoid switch, for controlling the flop gate actuator 1002 b.

By example only, the articulating structure 40 a comprises a feature selected from a group consisting essentially of a hinge, a pin, and a ball and socket combination. The at least one footpad 50 comprises a corrugated surface 50 c at the lower surface 50 b for minimizing surface tension of the leafy produce 10 which facilitates release of the leafy produce 10 from the footpad 50 when the plunger 30 retracts. The corrugated surface 50 c comprises a configuration such as a sinusoidal profile and a square wave profile, the sinusoidal profile being preferred. The at least one actuator arm 40 comprises a structure for adjusting stroke (not shown), wherein the stroke is effected by programmable logic control (PLC), such as a magnetic read switch disposed on the actuator arm 40 and a PLC-defined dwell time. The actuator arm 40 comprises an actuator arm housing 40 b such as a hollow tube. The at least one footpad 50 comprises a structure for adjusting size (not shown), especially the planform size. The footpad size adjusting structure comprises a feature such as at least one retractable footpad portion and a set of interchangeable footpads 50 which are interchangeable by loosening a fitting 41 a at a proximal end of a guide-rod 41 and a fitting 50 d at the upper surface 50 a of the footpad 50, wherein each footpad 50 of the set comprises a distinct size.

Preferably, the plunger 30 is angularly disposed in relation to the tray 10. The plunger 30 is activated, i.e., deployed by a feedback and control unit comprising sensor 110 (discussed, infra), upon sensing the presence of a tray 20 and retracted upon packing the tray 20 with the leafy produce 10. The apparatus 100 comprises a primary plunging mechanism 31, as shown and described, infra, with respect to FIG. 12. The footpad 50 is preferably selected to fit the size of the opening of the tray 20. In particular, as the footpad 50 reaches the bottom of the stroke, a puff of gas, such as air and nitrogen (N₂), as well as an inert gas, such as helium (He) and argon (Ar), is administered through a manifold disposed at the periphery of the upper surface 50 a of the footpad 50. After the dwell period has lapsed, the plunger 30 retracts; and the filled tray 20 is stepped forward by the conveyer 60 for applying the lid 130.

By example only, the present system 1000 further comprises a tray denester 140 (not shown) which removes two trays 20 from two magazines 150 (not shown) using a vacuum technique, such as air suction. The tray denester 140 receives a signal for supplying the trays 20 to a conveyor 60 having a stepper 70 (not shown). The vacuum technique involves a vacuum device (not shown) such as a cam and cylinder apparatus which travels upward to the waiting trays 20, contacts the bottom of the trays 20, pulls two trays 20 on a downstroke, releases those two trays 20 on the conveyor 60. The gas puff facilitates alignment of the trays 20 on the conveyor 60. The conveyor 60 runs the length of a processing line which may be twenty-five feet, for example, and is operated by a control panel (not shown) that imparts a signal which indicates the stepping distance for the conveyor 60, as shown and described with respect to FIG. 12, infra.
